Aqua Clara

What Aqua Clara does

Aqua Clara Kurume (アクアクララ久留米), legally 有限会社ケイティ商事 (KTI Shōji), is a privately held franchise partner operating under the Aqua Clara Group (アクアクララグループ) franchise system led by parent company Aqua Clara K.K. (アクアクララ株式会社). The company is headquartered in Fukuoka Prefecture, Japan, with a headquarters in Hakata Ward (Fukuoka City) and an operations/sales office in Hirokawa Town (Yame-gun), and operates with 1-10 employees. Its stated business is the sale of soft drinks and home delivery of bottled water, concentrated on the Kurume area and surrounding municipalities across Fukuoka Prefecture.

The company's core product is "Design Water," produced via reverse osmosis (RO) membrane filtration through 0.0000001mm pores that strip nearly all impurities, then re-mineralized with a proprietary four-component blend (calcium 9.8mg/L, sodium 5.0mg/L, potassium 1.7mg/L, magnesium 1.2mg/L) yielding soft water at hardness 29.7 and pH 7.3. Water is delivered in reusable 12L and 7L returnable bottles on a recurring subscription, paired with rented water servers (Aqua Advance, Aqua Slim, Aqua Slim S, Aqua Fab, Aqua With) that dispense cold (5-12°C) and hot (80-95°C) water on demand. The premium Aqua With model integrates with Nestlé Nescafé Gold Blend Barista 50 and Dolce Gusto Genio Io coffee machines. Accessories (three-tier racks, stackers, powder stockers, carrying bags) complete the catalog.

Revenue is generated through monthly server rental subscriptions (1,100-3,300 yen depending on model and plan length) plus per-bottle fees (1,188-1,728 yen), with two-year plans offering 13-15% discounts and lower minimum-order friction. Distribution is direct-to-consumer via the Aqua Clara Partners franchise network, with scheduled area-specific delivery days across Kurume city center, northeast/southwest Kurume, Ōmuta via agent, and roughly 15 other municipalities in Fukuoka and Saga Prefectures. Marketing and ordering rely on the corporate website (aquaclara.biz), the online portal (aquaclara-svr.com), the phone order center (0120-969-225, Mon-Fri 9:00-17:00), and in-person contact from delivery personnel ("Aqua Clara Porter").

Direct peers

• Crystal Liner (クリスタルライナー): Japanese home-delivery water server brand operating on the same subscription model with similar server hardware and bottled water product. Direct overlap in offering, customer, and channel.
• Mitsumata (ミツウロコ / Mitsuya Water): Established Japanese water server subscription operator serving households with bottled water and rental dispensers. Closely comparable business model (subscription + server rental + bottle delivery) and customer segment.
• Frecious (フレシャス): Direct competitor offering RO-filtered and natural water on a server subscription basis to Japanese households. Closely comparable product (server + recurring bottled water delivery), target customer (families and individuals), and business model (monthly subscription).
• Aqua Clara K.K. (アクアクララ株式会社): The parent franchisor of the Aqua Clara brand in Japan. Comparable because it operates the same water-delivery subscription model with the same RO + mineral 'Design Water' product and the same server lineup; Aqua Clara Kurume is a single franchisee of this national network.
• i Water (アイ・ウォーター): National water server subscription service in Japan using RO filtration. Comparable product offering (filtered water + server + monthly subscription) targeting similar Japanese household customers.

Broad incumbents

• Premium Water (プレミアムウォーター): Largest home-delivery water server brand in Japan. Comparable because it sells the same category of product (bottled natural water + server subscription) to the same household customer base; differs in being a national premium-positioned incumbent with substantially greater scale and marketing budget.
• Suntory Natural Water Server (サントリー天然水サーバー): Beverage-giant-backed water server subscription offering using Suntory's natural mineral water brand. Comparable category and customer; broader incumbent with much larger corporate parent (Suntory) and brand awareness.
• Kirin Aki no Megumi (キリン 秋の水サーバー / キリンのい・ろ・は・す): Major Japanese beverage company's home-delivery water server offering. Comparable in product (bottled water + server subscription) and customer base, with much greater corporate backing and national distribution.

Regional players

• Hita Tenryosui (日田天領水): Kyushu-based (Oita Prefecture) natural water brand with home-delivery offering. Comparable in operating a bottled water + delivery business, but regional Kyushu player rather than a direct head-to-head competitor in Aqua Clara Kurume's specific Fukuoka/Saga footprint.

Emerging players

• Coedo (彩雲 Miyabi / Coedoshizumountain): Smaller Japanese premium water and server subscription brand. Comparable in product/category (bottled water on subscription with server) but operates at smaller, more boutique scale than national players.
